Evidence-Based, Quantitative and Qualitative Research

This guide is a basic introduction to finding Nursing and health literature with a qualitative or quantitative focus.

Quantitative Research

Quantitative research is based on statistical types of data that can be accurately counted and measured, while qualitative research is more interested in people's experiences. This type of research will:

  • Describe with numerical data and statistics
  • Give statistical results
  • Make predictions 
  • Will be objective 
  • Will study randomly selected groups
  • Systematically test a theory 
  • Uses numbers
  • Uses a survey 

Quantity = numbers = quantitative

  • May use words such as random or randomized, control
  • May include numerous statistical tables and use statistical language as well as charts and graphics
  • Data is numbers-based (not narrative based).
  • May have multiple populations (ex. child and adult)
  • Data from structured questionnaires or interviews
